The Elon-buying-Twitter thing has been a fiasco for all parties involved (except maybe those who sold calls like crazy during the pop). The tinted region indicates his original purpose price, which was the Beavis & Butthead-chortle-inducing $54.20. Get it? Heh.
A certain competing organization with a certain President some of you are so crazy about is enjoying Twitter’s problems, although I suspect this pop will be terribly short-lived.
As usual, though, Elon is taking it all with a sense of humor.
